Digital Signature - signature is invalid

[ryancairns]

Hi - I am creating a PDF using cdintf.dll version 3.0.0 and then signing it. I am getting the message "Signature is invalid: Document has been altered or corrupted since it was signed".

I was reading on the forums that you recommended using version 3.0.3 but I can't work out where to download it? Can you please advise?

Many thanks

We would need to take a look at the code and the certificate that is being used for signing the documents.

Version 3.03 can be downloading by logging-in to the customer section, it is not available for general download.
